That _IS_ essentially what the patent claims. Ptacek tried to add specificity by pointing out that Apple essentially added the disclaimer "on a computer", which is of marginal usefulness.
His original response was wrong, and was the classic alluding to some deeper (but never stated) meaning to the patent. There is no deeper meaning. That is it.
What the patent claims is a device that has every element of a claim. Not just one element, or some elements. If it doesn't have every element, it's not an infringement.
More handwaving, however. This is why we can't have nice things.
You are wrong. Ptacek is wrong. AND APPLE AGREES. How is this nonsensical side discussion still occurring? The specific example is one that Apple used, so...what is going on here?
